SECTlONAL sonnnzn ROLL. Application filed October so, 1922. Serial No.597,702.

To all whom z'tm-ay concern. machine full of liquid is squeezed between-Be it known that l, FRANK L. Fn'nnnsn, this pair of rolls in deliveringit fro-m the a citizen of the UnitedStates, residing at machine. IlVestford, in the county of Middlesex'and In the use" of these rolls therubber gets 5 State of Massachusetts, have invented anew 'worn and Wearsunevenly throughout the .6 and useful Sectional Squeeze Roll, of Whichlength of the roll, whichiis quite long. That the following is aspecification. "is the reason Why. they have been made in This inventionrelates to a sectional sections. These sections arefintended to besqueeze roll for use in securing and other replaced when Worn, butheretofore it has 10 machines, in which fiber or fabric is passed beendiflic-ult to get them off and on for this 65 between rolls to extractthe water or other purpose Without injuring the iron ringson liquidtherefrom.

circumference of theroll. When it is desired toremove one of thesesections one of the end plates is loosened and the iron rings can bereleased from the bushing very in}; also can. be removed very easily asit is cut all the way through to receive the key The new ring with itsrubber section is put on the bushing and together tightly as stated, Theiron ring removed is then supplied with a new ru ber section which isvulcanized to it throughout their contacting surfaces and in ges of thesection distance, as for example, about a sixteenth of an inch on bothsides. In this way theiron rings and bushings are not injured in the actof remounting and replacement, but they can be used over and over again.

Although. Ihave illustrated and described only a single form of theinvention I am the fact that modifications can be made therein by anyperson skilled in the art without departing from the scope of the,invention as expressed in the claims.

Therefore I do not wish to be limited to all the details of constructionherein shown and described, but what I doclaim is:. f 1. A squeeze rollhaving a shaft and made up of a series of rubber sections, rings onwhich said sections are vulcanized, bushings on the shaft on each ofwhich one of said rings isremovably mounted, and means for positivelyconnecting said bushings and ringsfto the shaft.

2. \i rubbercovered squeeze roll comprising. a shaft having alongitudinal keyway with a key therein, a series of tapered bushings onsaid shaft, each of said bushings having a passage to permit said key toproject through and beyond it, a series of iron rings located on. saidbushings and fitting into which said key projects, whereby the ironrings and bushings are positively keyed to the shaft, and a rubbersection vulcanized at the exterior surface of eachof said iron Each bushthe parts forcedrubber covered squeeze roll comprising a shaft having alongitudinal keyway with a key therein, a series 1 of bushings taperedon their outer surfaces all in the same directionand located onsaid'shaft, each of said bushings being. cut. all the way through topermit said key to project through and beyond them, a series of ironrings located on said bushings and. fitting their outer surfaces; eachhaving a keyway into which said key projects, whereby the iron rings andbushings are positively keyed to the shaft, anda rubber sectionvulcani'zedat the exterior surface of each of said iron rings, eachbushing having a circular head at its larger end and each ring having anannular recess into which the head fits for limiting the motion of thering on the bushing and spacing the rings. all at the same distanceapart.
